WILLIAM P. QUENTELL, OF NEV YORK, N. Y.

TYPE-WRITER.

1'0 all whom it may concern: Be it known that LWILLIAM P. QUENTELL, of New York city, New York, have invented certain new and useful Improvements in Type-\Vriters, of which the following is a specification. v This invention relates to that class of type writing machines wherein the type characters are mounted upon a rotary and oscillatory support, preferably cylindricalin form, andin which the series of key-levers operate, first, through interposedcams and suitable gearin g to rotate the type-holder, so as to bring the desired character opposite the printing posi-' tion, and, second, by their continued movement to oscillate the type-holder, whereby to move it into printing position and effect the printing. 1 4

The invention consists in certain novel devices and combinations of devices, as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view with the ends of the key-levers broken away. Fig. 2 is aside elevation, partly in section and with parts broken away. Fig. 3 is also a sectional elevation showing the type-holder in the printing position. Fig. 4 is a front elevation of the type-holder, its" supports, and a locking-cam used in connection therewith. Fig. 5 is a top or plan view of the gearing for rotating the type-holder.

construction of the button end of the keylever.

In-the drawings, represents the base of the machine, 1 near the sides of which are standards 11 12, to the edges of which are secured vertically-slotted plates 13 14. A rockshaft 15, pivoted in the standards 11 12, affords a pivotal support for a series of keylevers 16, said key-levers being preferably stamped out from sheet metal and of ap proximately the outline shown in the drawings, Figs. 2, 3, and 6 These key levers work in the slots of the plates 13 14, and are therefore steadied in their'movements. The front ends of the key-levers are upturned, as shown in Fig. 6, and their extremities are provided with the integral disks 17,-forming the support for the letter-tabs 18, which may be of Patent No. 607,193, dated July 12, 1898. Serial No. 684,446. (No model.)

paper and have the lip 19 to engage within the notch 20 of the disk 17. The tabs are covered with a sheet of celluloidor other transparent material 21, and the edges ofthe several parts are protected and united by the band 22, which maybe of metal. The forward ends of the key-levers are bifurcated and the arms thereof are marked 23 24. The arm 23 has the oblique cam-surface 25 and the arm 24 has the oblique cam-surface 26. The arm 23 operates to rock a pivoted bail 27, and the arm 24 operates to 'move a plate 28. The plate 28 is supported upon the parallel pivoted arms 29, two of said plates being employed and each having oblique cam-slots 30 therein. The front edge of the bail 27 has its ends beveled, as shown at 27 27", and said beveled surfaces extend in planes which intersect the planes of the slots 30. The bail 27 is provided with a lug 31, which operates a pivoted stop-arm 32. Said stop-arm projects forward into the path of a rotary cam 33, through which a shaft 34 passes, the lat ter being slidably mounted in an oscillating frame 35, which is pivoted upon the standards 36. The cam 33 is tubular and cylindrical and constructed in a single piece, its contact -points being disposed in a plane oblique to its axis of rotation, or, in other words, being determined by the cutting of its cylindrical body'by'a plane oblique to the axis of the cylinder, the contact-points being thus located at different heights, and the cam may be stepped or serrated, as shown. The determining plane lies in equal halves on 0pposite sides of a vertical plane through the axis of rotation of the cylinder, so that the contact-points occupy the entire edge of the cam and are located in equal and symmetrical halves on opposite sides thereof. The stoparm 32 moves in a direction substantially parallel to the axis of the earn.- The shaft 34 also carries at its upper end a type-holder 37, having thereon three circumferential rows of type characters. The 'type wheel 37 has a collar 38 secured thereon, and said collar turns in a groove 39 in the shaft. The type v wheel or holder is turned upon the shaft by means of a pinion 40, sleeved upon the shaft and engaged with the rack-segments41 42, which are pivoted upon the frame 35. The

arms of said segments are drawn back by the springs e3 and are held in alinement by pins 4% thereon, which engage with the shoulders of a mutilated disk 15, secured to or formed integrally with the base of the cam 33. The gear-segments are moved by means of the plate 28, which has an extension 46 and a pendent pin 47, engaging with the segmentarm. A bail 48 is hung upon the shaft 15 and has a forwardly and downwardly extending arm 49, engaging loosely the lower end of a pivoted locking-dog50, said dog being pivoted at 51 on the swinging frame 35. On the shaft 34 is also loosely mounted a toothed lockingdisk 52, with which the upper end of the dog engages during one part of the operation, and the rocking frame 35 has a slotted guide 53 for the forward end of the stop -lever 32. The lockingdisk 52 is secured to a drivingarm Min the form of a flat bar, the lower end of which is secured to the cam-disk 33 and projects through an aperture in the lower surface of the type-holder 37, and thus when the pinion or gear 40 is turned it carries with it the mutilated locking-disk, the cam, the serrated or toothed locking-disk 52, the driver 5i, and the type-holder 37, said several parts moving as one. In order to steady the swinging frame 35 and the type holder, I show a second locking'dog 55, which is mounted in a slot or groove in a standard 56, so that while rigid in one direction it may yield in the opposite direction and engaging with the notches of the disk 52 the latter will be securely locked 011 opposite sides of its. axis of rotation. A sliding paper-carriage 57 is mounted in the rear of the type-holder and has journaled therein the platen-roll 58, the tension-roll 59, and carries the paper-clamps 60 and 61.

62 represents the paper.

In order to ink the type, I have mounted an ink-roller 63 on the end of the curved springarm 64.

The base of the paper-carriage is provided with a toothed rack 65, and a pivoted lockingdog 66 normally engages the teeth of the rack, said dog being connected by the cord or wire 67 with one end of a bell-crank lever 68, pivoted on a suitable support, and having its other arm extended over the bail 48.

In order to space without printing, I have shown a space-key 69, which is connected to the bell-crank 68.

In order to bring the several rows of type into printing position, the shaft 34: is, as before described, mounted so as to slide in the frame 35 and through the several parts of which it constitutes the axis-namely, the pinion, the mutilated locking-disk, the cam, the driver-bar,and the toothed locking-diskand said shaft is normally held down by the spring 70, and it is raised by means of an arm 71, through the intervention of the levers 72 73, which are shown in section in Fig. 4: and in plan view in Fig. 1. oted at one end to the frame 35 and inclines Said arm 71 is piv-' toward its opposite end, so that the levers 72 73 engage therewith at diiferent elevations. The ends of said levers are also curved in an arc concentric to the axis of the swinging frame 35, and by their depression the shaft carrying the type-holder is raised in its bearing, thus elevating a new row of type into the printing position.

The operation of the parts above described is as follows: Upon the depression of any one of the key-levers its arm 23 will engage and rock the bail 27, thus moving the lug carried thereby and permitting the stop-arm to drop down into the path of the cam 33. The extent to which the stop-arm will descend is regulated by the distance from the center at which the key-lever engages the oblique front edge of the pivoted bail, and the cam itself, as

previously stated, may have its edge serrated,

as shown;. but it will be arrested whether serrated or not when it is turned so that it strikes upon the projecting end of the stoparm. By the same movement the arm 24 of the key-lever will engage through its camsurface 26 with the wall of the slot 30, and will therefore move the plate 28 forward, the latter preserving its parallelism with the base of the machine by reason of its form of support. This plate 28 will have a greater or less movement, depending upon the position of the key-lever which is actuated with reference to the center of the machine. The keylevers nearest the center of the machine will move the plate the shortest distance, while those farthest from the center will move it correspondingly greater distances. The extent to which this plate is moved forward regulates the extent to which the segments are swung upon their pivots, and consequently the extent of rotation of the pinion and its connected mechanisms, including the typehold er. The type characters will be arranged with definite relation to the key-levers, and consequently the depression of any particular key-lever will operate through the intervening and connecting mechanisms to turn the type-holder, so as to bring theappropriate character opposite the printing position. During the first part of the movement therefore the stop-arm is lowered. Then the segmentis shifted and the type-h0lder is turned until it is brought to rest by the engagement of the cam-disk with the stop-arm. By the continued movement the key-lever lifts the bail 48 and through its arm 49, acting on the lockingdog 50 below the pivot 51, tilts the frame 35 to the position shown in Fig. 3. During this movement the ink-roller is pressed out of the way and the type strikes the paper. The tilting frame 35 is returned to its normal position by a spring 74, and may be provided with the stop-arm 75, which contacts with the base of the machine. Several of the movable parts are also provided with springs to return them to their normal positions-such, for example, as the movable plates 28, which have the springs 76, the bail 27, which has a spring 77, and the stop-arm 32, which has a spring 78. The several k ey-levers are also normally held down by springs, as shown at 79.

While I have described the preferred construction, I may of course vary some of the details thereof.
